we have 3 Server of windows 2000 running active directory. Last day the
global catalog server was unavailable due to some reasons, in that time users
were unable to access the active directory from there PCs. When users were
logon, it hangs on the PC.

I want to know why it is doing such behaviour when other active directory
servers are available. Also how can we avoid such situations in which GC
server is not available but other active directory server is available.?
